Wave Sync Watch
Radio Watch Sync Tool
Free
Sync compatible radio-controlled watches from your speaker with NTP-corrected time and live signal data.
Wave Sync Watch helps synchronize compatible radio-controlled watches when tower reception is weak or unavailable.
The app generates a precise audio signal through your device speaker. When the watch is placed directly against the speaker, some radio-controlled watches can pick up the near-field signal through their receiver coil and decode the time pattern.
This is not a long-range radio transmitter. It is a close-contact speaker-based signal tool for watches that support standard radio time protocols.
Features:
- NTP-corrected live clock
- Manual NTP sync
- Automatic protocol selection by region
- Support for WWVB, DCF77, JJY40, JJY60, MSF, and BPC
- Standard and experimental output modes
- Live envelope preview during broadcast
- Real-time transmitted-data inspector
- Physical checklist before starting transmission
- Light and dark mode
